Ive been wanting to buy some throttle body spacers for a while but im scared instillation will cost me a fortune. Can anyone tell me how much they would cost and if it is even worth it... because some people told me it adds 15hp and other told me it adds like 5 so please help me out, also what other mods will increase power? thanks alot guys im a real newwbie

Installing a TBS could be done by a trained monkey.

However, they're a COMPLETE waste of money on any multi-port injected engine like ours. Only throttle-body injected or carbureted engines can see any benefit from a TBS.

thanks alot
